To all whom it may concern:

Be it known that we, FREDERIC C. Gnown and BENJAMIN I-I. DE HAVEN,citizens of the United States, residing at Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Cork-Pullers,

of which the following is a specification.

This invention relates to devices for extracting corks from bottles andother similar receptacles, and has more especial reference to animproved device of the character stated, whereby, the stopper will bepulled by suction means.

It is among the aims and objects ofthe V invention, to eliminate the useof the ordi nary form of extractor, which comprises an instrumentinsertible within the stopper, to which, when embedded within thestopper, a .pull of suflicient force, to cause the dislodgment of saidstopper,,is imparted.

This form of extractor is exceedingly obijectionable, due to the mannerin which the stopper is mutilated, rendering it unfit for subsequentusage and oftentimes, forcing the same downwardly, into the bottle.

The nature of the invention, more explicitly set forth, may be statedbriefly, to comprise a pump provided with suitable pistons and having acap member arranged upon the lower end thereof, the pump cylinder Theimprovements in'the details and arrangements of parts will be apparentfrom an inspection of the accompanying drawings, in connection with thespecific description hereinafter contained, and wherein the preferredembodiment of the invention is disclosed for the purpose of imparting aclear understanding of the invention.

In the drawings F'gure 1 is a fragmental side elevation of my improvedextractor partly in section as applied to the mouth of a bottle, and

Fig. 2 is afragmental end elevation there- V of showing the arrangementof the operating jaw with relation to the piston rods and cylinder. 7

Referring now more particularly to the drawings, wherein like referencenumerals refer to corresponding parts throughout the several views, weprovide a pump cylinder indicating the same by the numeral 1, the lowerportion of which is contracted as, at 2, and then flared outwardly toconstitute the substantially bell-sl1aped cap member 3. A bottom 4 issecured to the side walls of the cylinder 1 by means of a plurality ofscrews 5 which are passed therethrough at a point adjacent the saidcontracted portions 2, and have arranged therein, preferablyconcentrically thereof, an opening 6, which serves to receive thesuction controlled valve 7, the lower portion of which has attachedthereto, a cross arm 7 whereby excessive upwardmovement of the saidvalve 7 will be prevented. It will be noted thatv the opening 6 isprovided with a reduced portion, thus, forming an annular shoulder 8,, v

consequently providing for. means whereby the beveled portion of thevalve 7 maybe effectively seated thereupon. The upper end of thecylinder is open and normally re- .ceives thereover, a screw threadedcap 9,

having an air exhausting opening 10 formed therein, for an obviouspurpose. A piston head 11 having an opening 12 therethrough, whichopening is normally closed by'means of a flap valve 13, is arrangedinteriorly of the cylinder and adapted for longitudinal movementtherein. To provide for means whereby the piston head 11 may be moved,the rod 141- issecured to the upper face thereof and extends upwardlythrougha suitable opening arranged concentrically of the screw threadedcap 9 and has formed vupon its upper extremity, an elongated bearingelement 15, the purpose of which will be subsequently described. Toprovide for means whereby the neck of the bottle which we shalldesignate as a, may be positively engaged with the sides of the capmember 3,

thus affording an air tight connection, we preferably line the same witha resilient material, such as rubber or the like, asat 16, it hemgobvious, that the same will permit the close-engagement of the upperportion of thebottle neck a therewith and consequently, provide for thenecessary connection.

In order to provide for means whereby the cylinder 1 may be supportedduring the operation thereof, we aflix the same to the outer end of thejaw member 17, which member is. provided with handle portion 18,

and has arranged intermediate the ends thereof, an apertured lug 19. Asecond handle 20 is pivotally connected to the handle 18 by means of apivot pin 21 which is passed through the apertured lug and through asuitable opening formed in the adjacent end of said handle, the saidhandle 20 carrying thereupon, adjacent its plvoted portion, an upwardlycurved arm 22 the outer end of which is bifurcated to constltute thespaced apart arms 23 and 23, between which arms, journal a roller 24,sup porting the same in position by means of the pivot pin 25 which ispassed through the arms 23 and 23. It will be noted upon reference toFig. 1, that the roller 24. is received within the slotted portion ofthe elongated bearing element 15 and permitted to travel therealong.Thus, when the upwardly curved arm 22 is forced downwardly by means ofthe handlev20, the roller 24 will be moved forwardly in the elongatedslot of the bearing element 15 until it has reached the opposite endthereof. Upon upward movement of the arm 22, the rod 1 1 and piston head7 will be drawn upwardly, the roller 24 moving in the elongated slot ofsaid bearing element to its normal position. To provide for meanswhereby the arm 22 will be normally held in its lowermost position, Isecure thereto, a contractile coiled spring 26, engaging the lowerportion of said frame with the lower portion 17.'

In using my improved device the flaring cap portion is engaged with theneck of the bottle, thus causing an air tight connection therebetween,by means of the construction as heretofore described. Assuming that thearm 22 is in its lowermost position, the handle 20 is then depressedcaus ing the said arm 22 to be moved upwardly, consequently drawing thepiston rod 15 and the cylinder head upwardly within the cylinder 1 andconsequently, moving the valve 7 from its seat 8, thereby creating asuction within the space below said piston. Should'the stopper be butloosely seated within the mouth. of the bottle neck, this suction ascreated will be sufficient to withdraw the same therefrom. However, inthe event that the same is tightly sealed, the piston head 11 is thenforced downwardly again, by means of the handle 20, whereupon, the flapvalve 13 will be moved over the opening and allow the air to escapethrough the exhaust 10 arranged within the closure cap '9, it beingnoted, that the valve 7 during this movement, has remained upon itsseat, thus, closing the opening 5 and maintaining the vacuum within thecap 3. The piston head 11 is then drawn upwardly thus, exerting anadditional pull uponthe stopper and causing the same to b dislodged fromits seat within the bottle neck. It isof course understood, that thesuction may be increased in proportion to the number of strokes requiredto dislodge the cork from the bottle neck.

By forming the cap 3 substantially bellshaped, it will be obvious thatthe device may be adapted for use with bottles having various sizedheads.

While we have herein disclosed the specific embodiment of the invention,it will be ap parent to persons skilled in the art that the invention iscapable of embodiment in other forms and devices differing in detail andarrangement from that shown, as may be in keeping with the heretoappended claims.
